| 摘 要： | 本文重点研究大面积冬小麦遥感估产模型构建及其调试方法。通过分析冬小麦生长发育过程,对光、温、水、肥等必须条件需求规律研究的基础上,提出了以绿度指数、温度和绿度变化速率等因子,构建大面积冬小麦遥感估产模型。为了适应大面积遥感估产运行系统的需要,在变量获取及模型调试等方面进行了一些新的探索。

| Abstract: | This paper centers on development and calibration of winter wheat yield remote sensing model. After analysing the requirement of necessity for wheat growth such as sun light, temperature, water and fertilizer, we developed a winter wheat yield remote sensing model for large area based bn vegetation index,temperature change rate, greenness change rate, etc. To meet the requirement of operational system for estimating winter wheat production of large area using remotely sensed information, we developed several novel techniques in variable acquirement and model calibration. |
